3 ohms is pretty high, I'd use 2 ohms max.
The Pertronics has some quirks about it, but should still work well with
2ohms.
Another factory pertronics application uses a 1.2 ohm ballast, so I doubt
that
a 2 ohm could cause any damage to the pertronics unit.
I wouldnt use a ballast with the lucas sport coil.
It has smaller gauge primary wire, and has a higher internal resistance,
it does not actually have an internal ballast resistor, and adding one
to the lucas sport coil will result in VERY weak high RPM spark.
I am not aware of any coil that actually has an internal ballast resistor.
There are few applications that really could use the added voltage provided
by the lucas sport coil, and a stock alpine is not one of them.
Use a stock coil and a ballast resistor, it will work just fine.
